Sally continued to up the ante with her intake of HGH and weird growth hormones, way more so than I was comfortable doing. But Sally just wanted to keep getting freakier, and she got off on freaking people out. So she pushed the limits as much as possible.
One morning I caught her topless, staring in the mirror at her toaster-sized pecs. She had them flexed, and huge thick veins thicker than pencils bloated and wrapped around them. It was almost sickening, watching those square blocks of meat bloat with thick blue veins and rippling striations as she gritted her teeth, willing them larger.
“Check it out, bro,” she rasped through grit teeth. “Aren’t my pecs so fucking freaky?”
I stared and bit my lip, feeling my cock stiffen as I watched those meaty pecs bloat and ripple with freaky vascularity.
“Oh god, Sally, they’re fucking awesome!” I replied.
She released her flex and grinned. I could see the outline of her huge flaccid cock as her spandex bottoms hugged it tight against a waist-thick thigh. She peeled the spandex off slowly, and I saw her semi-erect cock spring forward. Her hormones were so supercharged, it was always in a state of semi-arousal, and she could flex it it to its full erect hugeness at will.
“Oh yeah,” Sally said, licking her lips as she eyed her freaky, vascular body. She flexed her abdominals and the grapefruit-sized bulges rippled with striations. Veins inflated to pencil-sized worms, feeding blood to her mid section. Her cock jumped, instantly fully erect, and slapped lewdly against her abs and between the inches-deep cleft of her rippling pecs.
“I’m horny!” she rasped. Then she opened her mouth and let her tongue, freakishly long now due to her abuse of growth hormones, reach out and slither around the apple-sized head of her cock. She moaned as she used her tongue to pull her huge cockhead toward her mouth. The muscles of her back convulsed as her mouth opened wide enough to swallow an apple whole, dripped with saliva, and slid onto her massive cock.
I saw her nut sack bulge as her balls bloated, filled with cum and twitching in anticipation. It was as freakish as the rest of her. Her balls actually stretched the sack taught, and I could see thick blue veins squirming all around it.
She grunted and moaned loudly as her nutsack bucked. Waves of pulsing sinew bulged as her cock throbbed and pumped buckets of cum directly down her throat. After what seemed like minutes, she released her cock. It fell, semi-flacid, to hang down near her knee.
Sally licked her lips and smiled at me. “Enjoy the show, stud?”
My cock was rock hard and standing at attention. It was huge, bigger than I thought possible at 14” with a girth like my wrist thanks to all the HGH and other chemicals I was taking. I had gained muscle mass, too, tipping the scales at 240 lbs of solid beef. But I was still smaller than Sally.
I watched the rippling muscles of her bloated legs cascade with freakish vascularity as she stalked toward me with her 260 lb body. She was several inches shorter than me, and she was now wider than she was tall with meat wings for lats and traps that swallowed her neck.
Her hands roughly grabbed my waist and in an insane feat of muscular strength she hoisted me up above her head, letting the tip of my enormous engorged cock dangle above her lips. Then she opened her huge mouth wide and lowered my giant cock into it right up to the hilt.
I moaned loudly as her long tongue slithered out and bathed my balls in saliva as her throat muscles constructed. She sucked with the force of a vacuum and I groaned, cuming almost instantly at being so easily overpowered by my super muscular sister. I pumped what seemed like a gallon of cum directly down her throat. She gulped and swallowed every last drop.
She dropped me roughly and licked her lips, then said, “Get the gear. I need more juice!”
My mouth agape, I wanted to protest. She had just started a cycle so pumping even more roids into her body seemed dangerous.
Seeing my hesitation, Sally said, “I can handle it, babe. Just look at me!”
She flexed into a most muscular pose. Her traps rose, nearly touching her ears. Her alien pectorals filled all the space between her shoulders and jutted out by inches. Bowling-ball sized biceps pressed into them, and grapefruit-sized bulges visibly swelled from her abdomen. She looked like a raging muscle beast rather than a human woman.
“And I’m going to get bigger,” she said through grit teeth. “Bigger than the biggest, most muscular man on earth! Bigger than a GOD DAMNED GORILLA!” she cried.
I hurried to comply, injecting her with more juice than should be safe for any human. But her system just absorbed it willingly.
“Oh yeah,” she moaned, looking in the mirror, “I can feel it, babe.”
She flexed up a bicep and it rose, incredibly striated and rippling with thick blue veins.
“I can feel the man-juice, I’m more manned up than ten mortal men!” she said lustily, reaching down with her other hand to stroke her cock. It lengthened and thickened, bulging ominously.
Suddenly, she let out a roar, and flexed down mightily into a most muscular pose. I heard a sound like stretching rubber as every muscle on her body seemed to expand on her command. Her head was practically swallowed by the rising trap muscles and her back thickened further. Her lats forced her arms to nearly 45 degrees and her biceps grew by inches.
“SO FUCKING BIG!” she screamed as her cock bloated and stretched, thickening to the size of a baseball bat. It stretched sickeningly huge, right to the height of her head. Her balls bulged further, stretching her nut sack and straining with veins.
She brought her arms together, enveloping her huge cock, crushing it between her ludicrously thick arms, pecs, and abs, then bucked her hips. She felt electric shocks through her body as her giant cock rubbed up against her own muscles. She bucked again, harder, then again, then faster. Her eyes rolled into the back of her head at the amazing ecstacy of fucking her own muscles with her gigantic cock.
I watched in awe as she bucked one last time, roared, and came like a fountain.

Really good. I'd love to see the siblings go to town on Karen. Maybe even knock her up.
